Who Makes The Most Insulated Garage Doors?

Tue Feb 07, 2012 12:58 pm

Our bedroom is directly over our garage and looses a lot of heat because the garage door does little to keep heat in. Also, we figure with a good garage door that it shouldn't be that hard to keep the Leaf above 45-50 degrees F in the winter, which seems to be a sweet spot for cold whether range/charging.

Does anyone have suggestions for a garage door that truly has a good R rating. Most R ratings on doors are for the middle of a given panel and do not reflect how well sealed the panels are at the seams. We are willing to pay extra for a good door if it's worth it.

I don't think replacing the garage door would change the temp. that much to justify the expense. There are however kits you can buy to insulate the interior side of the door itself. or you could go to home depot and get a couple insulating panels of "Celotex" and cut them to size and glue to the back sideof the door.

I also forgot to mention that the door is on it's last legs and needs to be replaced, the motor is almost shot. I wouldn't do it just for the energy savings.

There was a Holmes on Homes episode recently with a situation similar to yours. He ripped the drywall off the garage ceiling and had blue foam insulation sprayed on the underside of the floor. Either that or they tore the whole house down and started over, I don't remember for sure now.

Heating Garages:

Most garages, expected to house gas-breathing cars, have substantial air vents down low, at least along one side wall.

Many do not have finished or insulated walls and overhead.

Air leaks around the top, sides, and bottom of many garage doors can be substantial.

The garage doors and windows (if any) often have leaks or very low (single-pane) R-values.

The Garage door panels should be insulated, but the "weather stripping" is also very important. If they say "it can't be done", find another installer that WILL do it.

Remember, heat rises and cold sinks, even after you have stopped all the "drafts".

If you have no insulation in the floor you can have it blown in without removing the rock.

Mikey loves the spray foam!
I noticed you're still working with polymers.

One of the reasons I ask is that I read the following article and it sounds like non of them really come close to the stated R-value.

We noticed a big difference in heat retention, especially with 2 ice cars on a hot summer day. So much so that we had to keep the door open for a couple of hours till the cars cooled down. We replaced 20 year old wood doors with metal insulated. Garage is attached and under bedrooms, insulated walls and ceiling.
